Dear Sir or Madam, We are a supplement company in Netherlands producing several types of health oils to be ingested orally using a disposable syringe with tip cap of 10ml size. We are not happy with our current supplier for several reasons but mostly because the tip cap is too loose and easily falls off. A cap that be screwed on would be optimal Therefore we are wondering what product options you could offer, and we would need a small sample to make an assessment. Sincerely, Olav S. Sovik Show More
